Physicum seminar

On Tuesday, 06. June, 2023 at 2:15 p.m. in Physicum A106

Chemistry with waste plastic: pollution remediation, oxygen harvesting, and solar energy utilization

Dr Matthias Weiszflog ja Inga Goetz (Uppsala University)

3D printing of metallic glasses and composites (Inga Goetz):
Printing can circumvent cooling rate limitations of traditional techniques to produce bulk metallic glass parts. The additive process can additionally be used to tailor structure, chemistry, and properties at selected positions on a component and envision different types of customized composites.

Neutron diagnostic for fusion plasmas (Matthias Weiszflog):

Neutrons from fusion reactions provide information on the fusion rate and plasma temperature as well as on the spacial and energy distribution of the fuel ion. Their detection requires sophisticated and well characterized instruments. Detection and calibration techniques will be discussed.

Collaborative physics teaching:
Starting from course adaption during the COVID pandemic, we describe our journey from remote laboratories to interdisciplinary virtual exchanges and future plans in collaboration with Tartu University.


The Physicum seminars are meant for a broad auditorium of physicists and materials scientists, as well as for interested people from other natural and exact sciences (including bachelor level students) and aim at introducing what is important and new in a certain field, or where a specific research direction has reached today.

Seminar is in English. Everyone is welcome to participate.
